As a key instrument for minimally invasive surgery, puncture needles have extremely high requirements for edge sharpness, surface finish and biocompatibility. With its non-contact and high-precision characteristics, laser cutting machines break through the process limitations of traditional mechanical grinding, inject innovative power into puncture needle manufacturing, and help the medical industry upgrade to a safer and more efficient direction.

 

The tip of the puncture needle needs to have an extremely fine edge to reduce tissue damage. Laser cutting uses ultra-fast pulse beams to achieve nanometer-level precision bevel cutting on medical stainless steel or nickel-titanium alloys. The edge is smooth and burr-free, avoiding microscopic cracks caused by traditional processes, significantly improving the puncture success rate and patient comfort.

 

Biopsy needles, anesthesia needles, etc. often require drug channels or sampling grooves to be processed on the inner wall of the needle tube. Laser equipment uses three-dimensional dynamic focusing technology to complete micron-level channel etching in a tube with a diameter of 0.3mm, realize integrated functional structure molding, and avoid the risk of contamination caused by multi-process assembly.

 

The laser cutting machine has a small thermal impact, avoiding high temperature carbonization damage to polymer coatings (such as polytetrafluoroethylene), ensuring the smoothness and biocompatibility of the needle body. Femtosecond laser processing can also retain the oxide film on the surface of the titanium alloy needle body, enhance corrosion resistance, and extend the service life of the device.

 

The laser system integrates visual positioning and automatic feeding modules to achieve high dimensional consistency in mass production. At the same time, the mold-free process supports rapid changeover to meet the agile development needs of customized needles.
